Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a bed body and a toilet provided on the bed body, and a mixer room and a drying room are connected to the toilet. The present invention relates to a bed for a physically handicapped person which can perform all the functions of urinating, automatically, simply and hygienically dispose of excrement, and which is easy to install.

Beds for people with physical disabilities, such as bedridden medical patients and people with physical disabilities, should be able to do all their own toileting without having to be cared for by others. It will be done.

This kind of bed has an opening in the center of the bed mat that allows the user to move his or her buttocks into the opening and use the toilet to defecate, while also temporarily storing excrement in the toilet bowl. There are two types: one that you leave in, and one that allows you to wash away your excrement with washing water after defecating. However, in the former case, the excrement in the toilet tank has to be frequently disposed of, which is a hassle, and there is a risk that an odor may permeate the room, making it unsanitary. On the other hand, the latter requires large-scale drainage equipment, which not only takes time but also increases equipment costs. The present invention aims to provide a bed for the physically disabled that can solve these problems, and one embodiment thereof will be described below with reference to the drawings.

In the figure, a bed 1 for a physically disabled person according to the present invention includes a bed body 2 and a toilet bowl 3 provided on the bed body 2,

In this embodiment, as shown in FIG. 3, a partition plate 34 is provided at the lower end of the toilet bowl 3, which can be opened downward and partitioned off between the toilet bowl 3 and the mixer chamber 5 by closing.

The partition plate 34 is configured to be opened by operating a switch after using the toilet, and automatically closed after excrement has fallen into the mixer chamber 5 and the buttocks have been washed. For people with severe physical disabilities who are unable to operate the switch, a detector detects when the user has finished using the toilet and the partition plate 34 opens automatically, followed by washing the buttocks and blowing hot air. After that, the partition plate 34 is closed. The drying chamber 6 is formed as a rectangular parallelepiped container made of cast iron or the like and heated to a predetermined temperature by a heater H, which is an electric heater, for example.

Further, one side wall 41 in the longitudinal direction of the drying chamber 6 is provided with a window portion 42 whose lower edge is flush with the bottom plate 37, and the window portion 42 is connected to a lid whose upper edge is hinged to the one side wall 41. A plate 43 allows the lid to be closed. Note that a suitable number of small holes 45 are bored in the cover plate 43. Inside the drying chamber 6, a sliding plate 47 is provided which moves forward and backward with respect to the window portion 42 as a hydraulic cylinder 46 expands and contracts. The sliding plate 47 can move forward and backward while its lower end is in contact with the inner surface of the bottom plate 37. Note that an edge 49 is formed at the lower end of the sliding plate 47. Further, the hole 51 provided in the top plate 50 of the drying chamber 6 and the discharge hole 36 of the mixer chamber 5 are connected to a conduit 52.
The conduit 52 is provided with a regulating valve 55 for guiding a mixture 53 of excrement, foam, and wash water present in the mixer chamber 5 into the mixer chamber 5 in appropriate amounts. Second
3, 56 is a container installed on the substrate 40 so as to receive the window 42 of the drying chamber 6 from below, and 57
is a stainless steel cover that covers the drying chamber 6 and container 56 so as to airtightly house them.

The cover 57 has an opening 59 for pulling out the container 56.
The front plate 60 of the container 56 has an opening 59.
Also serves as a lid to seal the In FIG. 1, 61 is a door attached to the housing 32, and the container 56 is taken out by opening the door 61. Further, one end of an exhaust pipe 62 is connected to the side surface of the cover 57, and the other end of the exhaust pipe 62 is the lower end of an exhaust pipe 63 that passes through the cover box 32 and is attached to the rear leg plate 9. They are connected nearby. Note that the exhaust pipe 63
The interior is filled with a deodorizing agent, and the deodorizing agent can make the exhaust air odorless. The storage box body 7 is moved up and down by lifting tools 65 installed close to both longitudinal ends thereof.

The elevating tool 65 screws the hanging screw shaft 67 of the deceleration motor m fixed on a Z-shaped support base 66 into screw holes 69 provided at both ends of the board 40, and The storage box body 7 is raised and lowered by reversing. In addition, the storage box body 7 is
As shown in FIG. 4, the mat 12 is raised to such an extent that the toilet bowl 3 is located within the opening 19 formed in the bent state. Note that when the toilet bowl is not in use, the small water tray 23 is in a deflated state, so the height of the toilet bowl 3 is reduced by the height of the small water tray 23. Therefore, the storage box body 7
The amount of elevation can be reduced. In FIG. 1, 70 is a table, and the table 70 is a
0 A column 72 that slides on rails 71, 71 provided on the outer surface
The bed main body 2 can be moved in its front and rear directions via the .
Further, on the front surface of the table 70, switches for operating the bending of the mat 12, opening/closing of the opening 19, etc. are arranged in parallel. However, when using the toilet, the opening 19 provided in the mat 12 is opened, the mat 12 is bent as shown in FIG. position. Then, while the storage box body 7 is rising, the hollow tube body 22 is filled with compressed air, and the hollow tube body 22 and small water receiver 23 are expanded. The bending of the mat 12 allows the disabled person to position his or her buttocks within the top opening 21 of the toilet bowl 3;
At this time, the hollow tube body 22 comes into close contact with the buttocks, and the upper edge portion 23a of the small water receptacle 23 also comes into close contact with the buttocks. Therefore, the physically handicapped person can rest his buttocks on the toilet bowl 3 in a comfortable and stable position, and can defecate inside the toilet bowl 3 without staining the mattress with water or the like. In addition, before using the toilet, foam for cleaning is discharged from the foam discharge part 26 into the toilet bowl 3 and the toilet bowl 3 is filled with the foam.
In addition, excrement such as small water is excreted into the foam, so the odor is wrapped in the foam and there is no risk of the odor wafting into the room when using the toilet.

The excrement is mixed with foam etc. in the mixer chamber 5 by the rotation of the rotary blades 35, and at this time the solid excrement is crushed into fine pieces. In this embodiment, when mixing in the mixer chamber 5, the partition plate 34 separates the toilet bowl 3 from the mixer chamber 5.
This ensures that odors are prevented from entering the room during mixing. A mixture 53 of excrement, foam, etc. formed in the mixer chamber 5 is supplied into the drying chamber 6 through a conduit 52.

The drying chamber 6 is heated to a predetermined temperature by a heater H, for example, 200℃.
Since it is heated to a temperature of about 0C, the adjustment valve 55
When the mixture 53 is supplied in small amounts, for example, about 10 cc, into the heated drying chamber 6 by automatic adjustment, the moisture evaporates almost instantly and the solid material becomes dry.
When moisture evaporates, a portion of the steam is discharged from the small hole 45 formed in the cover plate 43 into the space 73 formed by the substrate 40 and the cover 57, so that the pressure inside the drying chamber 6 becomes abnormal. can be prevented from increasing. When the solid material is almost dry, the hydraulic cylinder 46 is extended to advance the sliding plate 47 toward the cover plate 43, and the sliding plate 47 is moved forward toward the cover plate 43.
While opening the lid plate 43 at the upper end of 7, move the sliding plate 47 to the window 4.
Make it stick out from 2. The sliding plate 47 uses an edge 49 at its lower end to gradually remove solid matter adhering to the surface of the bottom plate 37, and as the sliding plate 47 protrudes from the window 42, the solid matter is removed. The solid matter falls into the container 56,
They are forced to be accommodated. Note that by opening the lid plate 43, the steam in the drying chamber 6 is discharged into the space portion 73. The discharged steam is temporarily stored in the space 73, and a part of its retained heat is given to the drying chamber 6, after which it passes through the exhaust pipe 62 and is discharged from the exhaust pipe 63 into the room in an odorless state.
In the drying chamber 6, this series of operations is repeated. Note that the switch of the heater H is temporarily turned off when the drying chamber 6 is heated to a predetermined temperature until the series of operations described above is completed.
It will completely cut off when it runs out. After using the toilet,
The toilet bowl 3 is lowered through the opening 19 by lowering the storage box body 7, and at the same time, the air inside the hollow tube body 22 is exhausted and the small water receptacle 23 is deflated (as shown in FIG. 3).

Thereafter, the hydraulic cylinder 17 is contracted to place the mat 12 in a horizontal state, and the opening 19 is closed with the lid 20. As described above, the bed for physically disabled persons of the present invention includes a bed body and a toilet provided in the bed body, and as a result of having a mixer room and a drying room connected to the toilet bowl, it can be used for bedridden patients and physically disabled people. People with physical disabilities, such as free people, can easily relieve themselves almost in a lying position, and they can do all the urination themselves thanks to the hot water spout and hot air blower installed in the toilet bowl. I'll come.

Furthermore, excrement can be automatically, simply, and hygienically disposed of. That is, compared to the conventional system in which excrement is temporarily stored in a toilet tank, the frequency of disposing of excrement is extremely reduced, and the risk of odors being emitted into the room can be avoided, making it more sanitary. Furthermore, since the bed for physically disabled persons of the present invention can be installed simply by transporting it to a predetermined location, there is no need for any large-scale drainage equipment as in the past, and use can be started immediately. In addition, in the bed for the physically disabled of the present invention, the toilet is not movable, but is placed on the mat 1 of the bed body 2.
The mat 12 may be connected to the lower part of the opening 19 provided in the fourth part.
It may be set in a bent state in advance as shown in the figure.

If the toilet is movable, the toilet can be raised diagonally upward toward the opening 19 of the mat 12, if desired. Furthermore, the steam within the drying chamber may be vented outdoors. In addition, in the bed for physically disabled persons of the present invention, the mixer chamber is not limited to the one shown in the embodiment as long as it mixes the excrement and foam while appropriately crushing the excrement. Further, in the bed for a physically disabled person according to the present invention, it is preferable for a physically disabled person that the mat 12 has a structure in which at least the backrest portion 13 can be raised.
